Developing a Hybrid Web Container Application

Use the hybrid App designer to create the screenflows for the Flight List application. The Hybrid Web Container Application will be using the MBOs developed for getting the list of Flight from SAP database. The screen flow of the application is given below.

When the user starts the application they will see a welcome screen with a message. From there they will see a start screen where the user enters the Airline ID of the flight to get filtered list of flights based on the Airline ID. Clicking on flight from the list will bring the detail screen.

This is the 3rd part of this series. Other parts are:

Part 1- Setup Mobile Development Environment

Part 2- Starting SUP Development

Part 4- Deploying a Hybrid Web Container Application

Part 5- Register Device and Assign User for Hybrid App

Part 6- Test Application on Device

1. In the Sybase Unwired Workspace, create a new HWC application. Right click on the project> New> Hybrid App Designer.

7. Double click on the Welcome screen and change the OK action of the screen from Save to Cancel. Welcome screen is going to be the first screen of the app hence the OK action should be “Cancel” for an app with client initiated starting point.

Conclusion

Our simple HWC application has been built. The next step is to deploy this application to Unwired Server. Once this application is deployed to server it will be accessible to the mobile users. Go to Part 4 to deploy HWC application to Unwired Server.

    Greetings Midhan,

    Following the tutorial to this point, when I get to the point where it instructs to “Drag and Drop” the MKO object onto to “Flow Design Screen” to create the two screens “FlightList” and “FlightListDetail”, I only receive one of these screens, the “FlightListDetail” screen. Please note, I am using SMP 2.3.3 (SDK and Server). Could the issue be my version of SMP, or would there be another reason why it would only create the one screen?

    Thanks,

    Christoff Schwan

      An update to this issue:

      I recreated the MBO on previous STEP page. But instead of using the Search function to search for the BAPI, I manually browsed to “Basis Components->ABAP Workbench->Flights” to get the GetList function. Once the MBO was created in this fashion, when dragged and dropped onto the Flow Design, it created the expected 2 screens.

      Thanks,

      Christoff Schwan

      Sometimes this happens, I assume that its a bug. If you recreate the MBO or recreate the WF this issue will be solved.
